Abstract (en)

[origin: EP3398992A1] An ethylene-vinyl alcohol copolymer composition comprising: (A) an ethylene-vinyl alcohol copolymer; (B) a phosphoric acid compound; and an iron compound; wherein the iron compound is present in a proportion of 0.01 to 100 ppm on a metal basis based on the weight of the ethylene-vinyl alcohol copolymer composition; wherein the phosphoric acid compound (B) is present in a proportion of 1 to 100 ppm on a phosphorus basis based on the weight of the ethylene-vinyl alcohol copolymer composition. Therefore, the ethylene-vinyl alcohol copolymer composition has an excellent adhesive property with respect to a metal surface.
